Abstract
A semiconductor device where a plurality of DMOS transistors formed in a distributed manner on a semiconductor substrate can operate without being destroyed and a method of manufacturing the same. The on/off threshold voltage of a DMOS transistor at the innermost position from among three or more DMOS transistors formed in a distributed manner on a semiconductor is greater than the on/off threshold voltage of a DMOS transistor at the outermost position.
